- Create logging_config.py with get_logger() providing dual handlers:
- Console handler (stderr) controlled by GRM_LOG_LEVEL env var (default INFO)
- File handler (~/.local/state/grm/logs/grm.log) capturing everything at DEBUG
- Replace all print() calls in executor.py and report.py with logger.info()/error()
- Add error logging before raising AnsibleError in executor.run()
- Add GRM_LOG_LEVEL to README configuration table and logging documentation
- Update all unit tests to mock logger instead of using capsys
- 114 tests, 100% coverage, pyright clean, ruff clean
